COMMAND.COM 36254DF7023C09BC0E264F7E459EBAF8 VER command: The COMPAQ Personal Computer MS-DOS Version 3.00

Version History:

For a major release, there was little prominence to this version. To date, only Compaq, Zenith Data Systems, and perhaps AT&T, are known to have issued it despite rumors that several OEM vendors had agreements with Microsoft. This version included ENHDISK.SYS, Compaq's driver for hard disks that sized to 32MB (logical partition management beyond 32MB to come later with Compaq's MS-DOS 3.31 release). Like it's IBM cousin, MS-DOS 3.00 also added support for DSHD 5.25" media, as well as the ATTRIB.EXE command to manipulate file flags.
